In some embodiments, the modular construction kit 100 may includeapplication program interfaces (APIs) to interface with externalsoftware application. The modular construction kit 100 may alsocommunicate with a simulation program.

In some embodiments, the modular construction kit 100 includes ascripting language and a programming user interface (UI) for programmingthe operations, functions, movements, and the like, of the variouscubes. The scripting language may be designed to educate small childrenin robotics and logical thinking while being a fun sandbox environmentto play in, for example, as in a game. Using the UI, a user can create aprogram which may then be uploaded to a construction, for example, arobot, constructed with one or more cubes of the modular constructionkit 100. The program created with the scripting language may executeusing best effort, even when the logic of the program is flaw orcontradictory. The program thus may forgive mistakes and rewardachievements, allowing the user to see results and learn. In someembodiments, it may be possible to create random programs, the modularconstruction kit 100 can still cause the construction to function.

FIGS. 25-41 illustrate an exemplary embodiment of a programming UI 200of the modular construction kit 100. As described herein, theprogramming UI may be provided at a wireless device, for example, atablet, a laptop, a smart phone, or any wireless device havingcommunication capability (e.g., WiFi, Bluetooth, or RF). The programmingUI may include a Start UI 210, as illustrated in FIG. 25, where the usermay begin creating an application program. The Start UI 210 may includea Start bubble 212 and a blank field or bubble 214. Each blank bubble214 represents a logical step wherein the user can insert an availablecommand (which may also be referred to herein as command action, oraction) from the command menu bar 216. The commands may be grouped intocategories, for example, Motion, Looks, Sounds, Logic, Special,Triggers, and so on.

In some embodiments, the Motion category may include commands such asGo, Turn, Servo, and so on. In some embodiments, when the user selects(e.g., places a cursor over, or touches) a category, a command selectionwindow may be displayed. Referring to FIG. 26, exemplary embodiments ofsome command categories are illustrated. For example, commands under theLooks category may include command operating Light 1, Light 2, and LEDDisplay. Commands under the Sounds category may include Bark, Meow,Laser, Sound 1, and Record. Commands under the category Special mayinclude Photo, Push Notification, Infrared (IR) Blast, Temperature,Voice, and Laser. Commands under the category Triggers may includeButton, Obstacle, Temperature, IR, Noise, Motion, Light, and Position.These commands are illustrated as examples. Other commands for receivingand sending data from or operating the various cubes of the modularconstruction kit 100 are also contemplated.

FIGS. 27(A-C) illustrate exemplary operations of selecting a command,for example, Go (shown as an up arrow), for the first logical step (orbubble) or the program being created. In some embodiments, when a bubbleis filled, a new empty bubble may be created, for example, growing outof the filled bubble. An empty bubble may also be created by selecting(e.g., tapping) a small empty bubble 220, as illustrated in FIGS.28(A-B).

As illustrated in FIGS. 28(A-B), more than one action commands (e.g.,Move Forward, Turn Left, Blink Light, Take Photo, Play Sound) may beadded to one bubble. The modular construction kit 100 will function itsbest to execute these actions within one logical step. In someembodiments, these steps may be executed substantially simultaneously.As illustrated in FIGS. 28(C-D), the commands are displayed in a bubblewith a floating effect. When a new command is added into a bubble, theexisting commands are moved around (float) to create space for the newcommand. As illustrated in FIGS. 28(E-G), when a new command 222 isselected and dropped outside of a bubble, it is moved inside the bubbleand placed next to a nearest command. In some embodiments, a menu 224for the new command 222 may be automatically displayed.

As illustrated in FIGS. 29(A-D), actions may have degree of values,intensity or measurements. For example, rotation may be specified indegrees, move may be specified in centimeters, light may be specified inbrightness, blink may be specified in number per second, and the like.The degree of values may be a random value. For example, the user mayindicate a random value by using a touch-and-spread motion input of twofingers to indicate a random value within a range. The size of the roundcommand icon may vary with the degree of values of the action.

As illustrated in FIGS. 30(A-B), a user may tap on a displayed command226, a menu 228 may be opened, showing the stored value for the command226. The user may then change the value for the command 226. FIG. 30Cillustrates exemplary menus for the Sound category. In some embodiments,the user may also record a new sound.

As illustrated in FIGS. 30(A-B), a new chain of bubble 234 may becreated by selecting and dropping a command 230 outside of an existingchain 236. Chains of bubble may also be created and moved (dragged)around the program, as illustrated in FIGS. 31(A-B).

As illustrated in FIGS. 32(A-B), an action or entire bubble may bedeleted my selecting and moving it to the Trash Bin icon 240.

As illustrated in FIGS. 33(A-B), the modular construction kit 100 moveson to execute the next bubble 252 when all commands in a bubble 250 arecompleted and, for example, there is no special condition as describedherein.

FIGS. 34(A-D) illustrate an exemplary creation of a loop bubble(operation) 260, by drawing a circle around selected bubbles. The numberof times 262 to execute the loop 260 may be entered (e.g., x6 asillustrated).

FIGS. 35(A-D) illustrate an exemplary creation of an “if” chain(operation) 266, by selecting and dropping a command or action (e.g.,Clap) at the edge of a bubble 265. The “else” chain 268 (of theif-then-else logic) may then be the other bubble chain from the bubble265. In some embodiments, while the modular construction kit 100executes the action commands, it monitors the condition(s) of the “if”command. If the condition is met, for example, a clap sound is receivedor an obstacle is sensed, it stops executing all actions and moves tothe bubble attached to the “if”.

In some exemplary operations, when a user selects or presses the Start(Play) bubble 270, the program may be sent from the wireless device tothe modular construction kit 100. The modular construction kit 100 maythen execute the program step by step until the chain of bubbles ends,or when the user presses the Stop bubble 272, as illustrated in FIG. 36.

FIG. 37 illustrates exemplary embodiments of error handling. Forexample, some bubbles may contain contradictory actions, such as MoveForward 110 cm and Move Backward 95 cm, so that execution of the actionsmay not be possible. In these embodiments, the modular construction kit100 may display an error message, for example, “Oops, can't go forwardand backward at the same time.”). The modular construction kit 100 mayuse best effort to execute the action commands. In the example, themodular construction kit 100 may move forward 15 cm, and displays themessage “110 cm−95 cm=15 cm.” The modular construction kit 100 may notrequire additional action from the user and educates the user about howthe modular construction kit 100 interprets the commands.

FIG. 38 illustrates exemplary embodiments of duplicated actionshandling. For example, some bubbles may contain duplicated actions, suchas Rotate Right 90° and Rotate Right 15°. The modular construction kit100 may use best effort to execute the action commands. In the example,the modular construction kit 100 may rotate right 105°, and displays themessage “Rotate right 90°+Rotate right 15°=rotate right 105°.”

FIG. 39 illustrates an exemplary embodiment of a Wait command 280, asillustrated with a glass timer icon. When executing a bubble with a Waitcommand 280, the modular construction kit 100 may execute all othercommands in the bubble, then waits for the amount of time specified inthe Wait command 280. When the Wait timer expires, the modularconstruction kit 100 may move on to the next bubble. However, when thebubble also includes an “if” condition, as illustrated with condition282, the modular construction kit 100 may execute the “if” chain whenthe condition is met, although the Wait timer has not expired.

FIG. 40 illustrates an exemplary embodiment of an Infinite action, asillustrated with an infinity icon 286. An Infinite action may beexecuted indefinitely. For example, rotate indefinitely, move forwardindefinitely, and so on. However, when the bubble also includes an “if”condition, as illustrated with condition 288, the modular constructionkit 100 may execute the “if” chain when the condition is met,interrupting the infinite action.

FIG. 41 illustrates an exemplary program using the programming UI 200 ofthe modular construction kit 100. As described herein, a program may beuploaded to a construction of the modular construction kit 100 and maycause the modular construction kit 100 to operate autonomously.

FIGS. 42-55 illustrate an exemplary embodiment of a user-definablecontrol UI 300 of the modular construction kit 100. As described herein,the control UI may be provided at a wireless device, for example, atablet, a laptop, a smart phone, or any wireless device havingcommunication capability (e.g., WiFi, Bluetooth, or RF). The control UImay provide interfaces for a user to control a construction of themodular construction kit 100, for example, a robot. The control UI mayprovide a grid 310 where windows or boxes 312 may be created, forexample, by a user to represent the actions of the modular constructionkit 100. In some embodiments, the windows 312 may have predetermineddimensions. In some embodiments, the user may define the dimensions.

FIG. 43 illustrates an exemplary control UI of FIG. 42 with the windows312 filled with action controls, which will be described in more detailherein. In some embodiments, the windows 312 may be rearranged, added ordeleted. FIG. 44 illustrates an exemplary control UI with some windowsfrom FIG. 43 rearranged and some deleted.

FIG. 45 illustrates an exemplary side menu 320 provided by the modularconstruction kit 100. The menu 320 may provide action commands that theuser may select to fill into the windows 312. The actions illustratedinclude Motor 1 for representing a first motor action, Motor 2 forcontrolling a second motor cube, Servo 1 for controlling a firstservomotor cube, Play Sound for playing a sound at a cube with soundfunction, and so on.

FIGS. 46-48 illustrate exemplary control features and indications ofactivity or received status for some example actions. For example, FIG.46 illustrates exemplary control of, or status from some Motion categorycubes. The cubes may be put in a Static or Active state. Or the modularconstruction kit 100 may report the status of the cubes as in Static orActive state. Similarly, FIG. 47 illustrates exemplary control of, orstatus from some Sound category cubes, and FIG. 48 illustrates exemplarycontrol of, or status from some Special category cubes.

FIG. 49 illustrates exemplary control of, or status from some Visualscategory cubes. For example, an LED cube may be turned ON or OFF, orchange colors from a control window in the control UI. In anotherexample, an LED screen cube may be set up from a control window in thecontrol UI by tapping on the displayed circles to turn eachcorresponding LED of the LED screen ON or OFF.

FIG. 50 illustrates exemplary control of, or status from some Displaycategory cubes. For example, a Motion sensor cube may be turned ON orOFF, or may report whether a motion has been sensed by displayingdifferent statuses, a meteorology cube may report the read temperature,a light sensor cube may report the amount or intensity of light sensed,a sound cube may report the level of sound detected, and so on.

Some cubes of the modular construction kit 100 may provide selectableoutputs. For example, a sound cube may output different selectablesounds. As illustrated in the exemplary UI in FIG. 51, the control UImay provide a menu 350 for selecting a sound (e.g., Sound 1, Sound 2,Sound 3, Sound 4) to play. The menu 350 may also provide a Record button352 when the cube has a microphone to record sound.

FIG. 52 illustrates exemplary control menus for Special category cubes.For example, a control menu may be provided to control an IR cube toreceive IR signal from an external source.

Other control UI menus for other categories are also contemplated.

In some embodiments, the modular construction kit 100 may provideexternal control from an external device, e.g., a laptop or tablet, withgesture control sensors, such as those provided by Microsoft Kinect orLeap Motion, to have the user's movements control the motions ormovements of a construction.

In some embodiments, the modular construction kit 100 may includevirtual reality (VR) capability. In some exemplary operations, themodular construction kit 100 may stream images captured by a camera to aVR device, such as a headset. Movement of the VR device, for example, auser's head movement with a VR headset, may change the camera positions,so that the user may observe the area around the camera.

These and other embodiments of the modular construction kit 100 may becombined. For example, the VR capability may be combined with gesturecontrol and other features of the modular construction kit 100 toprovide the user with a fully immerse experience.
